The impact of last week’s heavy snowfall around Greece, prompting power outages in various areas, northern parts of Athens being hardest hit, has added credibility to state-controlled power utility PPC’s compensation bid to the European Commission for its need to keep using lignite-fired power stations.
Had IPTO, the power grid operator, not ordered the grid entry of PPC’s lignite-fired power stations, nowadays a high-cost option, widespread blackouts amid the adverse weather conditions would have been inevitable, making matters far worse, including at economic and political levels.
IPTO officials have stressed the country continues to need PPC’s lignite-fired power stations until their production capacity is gradually replaced by cleaner gas-fueled power stations. These are: PPC’s Ptolemaida V; a unit being developed by the Mytilineos Group in Viotia, northwest of Athens; and Terna’s prospective unit in Komotini, northeastern Greece, still at the planning stage.
The period between 2021 and 2024 will be crucial for the country’s power generating sufficiency as a result of the planned withdrawal of existing lignite-fired power stations, a related IPTO study has shown. The system’s sufficiency will depend on how swiftly the aforementioned gas-fueled power stations, totaling 2,150 MW, can be up and running.
If the planned completion dates for these three projects are maintained then there will be no reason to delay the withdrawal schedule of lignite-fired power stations, sources pointed out. The grid entry of PPC’s Ptolemaida V and Mytilineos’ Viotia unit, without the Terna unit, would suffice to cover the capacity gap to be left by the withdrawn lignite units, these sources added.
However, any delays in the completion of the new power stations could prompt Greek officials to request more time from the European Commission for the withdrawal of lignite-fired units, the sources said.
